And also a few tools if you don't have them already: at least a pair of long-nosed pliers and a small Philips and flat screwdrivers. Most pliers have cutters built in, but you should also get a pair of side-cutters and maybe also a pair of wire strippers.

And a soldering iron.....

Budget permitting, a kit of tools is a good idea, see pic below. But beware the quality: some of those kits are really cr@p, and the screwdrivers can only be used once before they become paint stirrers.

Look up the LED voltage for the LED, as in your list... Subtract that from the supply voltage that you are putting onto the LED and its resistor... Then divide that by the LED current, and the result is the resistor you need. Then choose one a bit higher, to cut the current a bit more.

For example say the LED is 2V and 20mA, and you have a 5V supply. You need tom lose 5-2 =3V on the resistor, which at 20mA (0.020A) gives 3/.02 = 150Ohms so use say a 220.

I got a Sparkfun resistor pack with 500 resistors of various common sizes.
